Title: Generating sync. signal for colour TV transmission - using memory for data of flank direction intervals, phase position, and result mode of sync. signal curve
Inventor: MUELLER JUERGEN DIPL ING
IPC: H04N9/44
Filed: 1990-03-09
Abstract: From a clock pulse signal, linked to a chrominance carrier frequency, an APROM (2) address signal is derived. The APROM stores data of time intervals, flank direction, phase position and type of sync. signal source results. In dependence on the address signal, the data values of the interval data are read out and supplied to a preselector counter (4). On reaching the applied interval data value, the counter transmits an output signal starting an up-down counter (5) controlled by a clock pulse signal. The data values at the counter output are added to parallel read-out interval data values via the respective phase position. USE/ADVANTAGE - Generating sync. signal with improved phase precision in real-time.
Patent DE-4021863-A1 (DE)
Title: Floor tile laying - uses an adhesive which expands on hardening to take up floor irregularities
IPC: C09J5/08
Filed: 1990-07-09
Abstract: To lay floor coverings, especially floor tiles, the adhesive used to bond the tile to the floor increases its volume during hardening, to take up irregularities in the floor surface. The adhesive expands under hardening, with the expansion pressure which is not greater than the specific gravity of the floor tile. The adhesive is applied at a rate so that at least 65% of the floor tile surface towards the floor is coated with the adhesive after harden ing. The adhesive is applied in strips either to the reverse surface of the floor tile or to the floor. The volume increase of the adhesive has a selected and defined value so that, with a max. 100% cover on the reverse surface of the tile, the reduction of the thickness through compression as the tile is laid is a max. of 40% of the adhesive thickness on application before the tile is laid. The tile can have a shaped plastics joint to give a keyed bond between the adhesive and the lower edge of the joint. The reverse surface of the floor tile can be fitted with recess strips to hold and align the adhesive and distribute the adhesive evenly over the tile surface. ADVANTAGE - The method gives easy floor tile laying, even when the floor is rough and uneven, to give a smooth floor surface.

Title: Rapid exchange coupling for water wheels - is of rhomboidal insert type and is used with drum-type wheels on horizontal shaft
Inventor: HORVATH SANDOR
IPC: F03B7/00
Filed: 1990-09-20
Abstract: The relatively small platform (8,10,11,13,18) is formed by iron plates welded together and rests on telescopically adjustable feet. Gables which are positioned opposite to one another are foldable to and from each other on the upper end of a link, and can be fixed in two positions by a welded plate (7). In their folded vertical position, they accommodate on both sides guide ball bearings (1,2,4,5,6,7,8,9,12,13,14,15,16,17,18) for the drum blade wheels. When the gables are folded downwards, they release the shafts (1,16) with end-located simple rhomboidal couplings (4,17). When the whole process is carried out, the drum blade wheels must be free from water pressure. USE/ADVANTAGE - As a rapid exchange coupling for drum blade wheels activated by water flow, so that a shaft extension can be effected in the shortest possible time.

Title: Packing plastics bottles with hot viscous fluids - involves drop of liq. gas to clear condensable vapours from dead space volume
Inventor: BABEL OLAF
IPC: B65B31/00

Title: Fuel gas prodn. from wastes contaminated with heavy metals - by partial oxidn. in presence of sulphur@ to convert volatilised metals to solid sulphide
Inventor: SCHLINGNITZ MANFRED
IPC: C02F11/00
Filed: 1991-04-12
Abstract: Combustible residues (A), polluted with heavy metals, are utilised by partial oxidn. with an O2-contg. agent in a high-pressure flame reaction to produce a crude gas rich in CO and H2 while at least part of the heavy metals are converted to vapour in this gas. The new feature is that oxidn. is carried out in presence of sulphur (in any suitable form) which is at least partly converted to H2S which becomes mixed with the crude gas. This gas is cooled with water under pressure (and becomes satd. by partial evapn. of water) so that H2S dissolves and reacts with the vaporised metals to form the corresponding sulphides which are sepd. as a sludge from the remaining (unevaporated) water. Enough S is used to provide an H2S partial pressure of at least 10 kPa and it is supplied to the oxidn. reaction together with (A). USE/ADVANTAGE - The method is applied to waste materials such as clarified sludge, used oil, drilling emulsions, etc. It provides simple control of volatile heavy metals and no metal-polluted waste waters are generated.

Title: Temp. controller esp. for engine induction air flowmeter - includes resistor bridge with high impedance measurement resistance, heating resistance and amplifier with voltage control loop
Inventor: LIEDTKE GUENTER DIPL ING
IPC: G05D23/24
Filed: 1991-09-13
Abstract: The temp. controller includes a resistor bridge circuit with a high impedance measurement resistance in one arm and a heating resistance in another with similar, esp. positive, temp. characteristics.

The amplifier output is connected to a load resistance. One control electrode (18) of the control transistor is connected to the amplifier's positive supply connection so that it is supplied via the control electrode. Deviations from the constant over temp. cause opposite variations in current drawn from the supply connection until the bridge is balanced. USE/ADVANTAGE - Esp. for air flowmeter in internal combustion engine induction system. Simplified controller with reduced number of components.

The lower end of the wetting surface (16) is at a gap from the end of the slit, with a flap (20) bent away from the yarn path to carry surplus fluid back to a catch container (24). The outlet opening (10) is at the base of the slit (8), near its outlet end, where a deflection edge (12) moves the yarn (5) at a small angle to the wetting surface (16). The deflection edge (12) is between the base (9) of the slit and a surface (13) pitched at a larger angle. A suction opening (14) is at the slit (8) below the outlet opening (10), connected to a suction channel (15) with a suction jet at its end to generate suction air in the channel at given time intervals. The fluid (F) is fed to the outlet opening (10) by a pulsating dosing pump with a variable frequency and/or stroke volume. A pressure compensation chamber can be in front of the outlet opening. ADVANTAGE - The appts. gives a high deg. of wetting to the yarn, when the yarn travels at high speeds.
